Prototyping with Cellular Modems and Modules

2022-03-26
Breadboards are great for quickly wiring together simple circuits like LEDs, logic gates, and even some low power microcontrollers. While simple to use, the external wires and internal electrical conductors do not work well with higher speed and higher power circuits because they are very high impedance. Instead of acting like low-resistance conductors, they behave like high-resistance conductors at high frequencies. High impedance conductors wreak havoc on high efficiency DC/DC converters and power amplifiers like the ones used in cellular designs. This document explains why this is a problem and give some solutions to those wanting to prototype fast.
